It has been believed for a long time that it is passive or vestyzial, scientists believe that the muscles behind the human ear really become active, when people listen carefully, according to a study published in a study Frontiers in neuroscienceThis muscle, known as the Erykulis posterior, has been largely passive in humans for centuries, but when individuals focus on challenging the hearing tasks, the rearness of the rearness shows.
“There are three large muscles (that) connect the Auricle (outer ear) to the skull and skull. The listener said. Germany.
For studies, 20 participants were recruited without any hearing problems and their auricular muscles were recorded as an audiobook using electromeography, along with using electromography, along with them distracting in front of or behind them. The one was played with podcast.
“Three different situations, each more difficult and more effort require, which requires listening in greater quantities, separating the number of distractor streams and the pitch as well as the signal-to-show ratio It was generated, “The study exposed.
As the difficulty level of work increased, therefore, also, better auricular muscle activity also occurred. Although they remained relatively inactive during easy and moderate tests, hard tests saw an increase in their activity.

Study conclusion
The results of the study mean that muscle specific circumstances may include enhancing hearing perception, possibly by adjusting the ear position to catch better sound.
Researchers stated that findings can also help us understand or develop treatment for hearing processing disorders where such muscle activity may either decrease or excessive.
“This may be worthwhile to detect ourular muscle activity to be used as a purpose metric to assess the effectiveness of the hearing aid algorithm to reduce listening attempt, because pinnas and pinnas. There is a clear physical relationship between hearing perception. “
Although it is unknown as to why these muscles took place 25 million years ago, researchers stated that “evolutionary pressure to move the ears shut down as we became much more efficient with our visual and outspoken systems”.
